( Basel, Switzerland. ) 

In the collections of Philippine ferns sent me by Elmcv D. MerriU, 
Botanist, of the Bnreau of Science, and by Dr. E. B. Copeland, which have 
increased in an unexpected manner since the year 1903, I have distin- 
guished very many forms not considered by Dr. Copeland in his papers on 
Philippine ferns,^ and which are not included in my two works on the 
fern flora of the Archipelago.- 

At the request of Mr. Merrill, 1 have prepared a list for publication in 
The Philippine Journal of Science, eontaining the diagnoses of those 
species that appear to me to be undescribed, and observations on others 
which for one reason or another are of special interest. I wish to express 
my sincere thanks to Messrs. Lolier, CopeJand and Merrill for having 
with great lil)erality supplied me with the rich material that has enabled 
me to undertake this work. 

Cuming's collection is the l^asis of our knowledge of the pteridophyte 
flora of the Philippines, and of which J. Smith^ published a list of 
species, however, unfortunatcly, containing many almost noniina nuda.

l'n'sl lias (lescribed many of tlic spccie.s represented in (himinf/s eol- 
lection* in a masterly nianner, biit perhaps has carried the separation 
of species a littlc too far in somc cases, altliough his obscrvations are very 
exact and his dcscriptions vcry clear. In working on Philippine ferns,, 
it is always necessary to consnlt this worlv in detemiining whether or not 
a species has been described. 


1. Hymenophyllum Merrillii n. sp. 

Leptocionium, ex afhnitate II. holochili (v. d. B.) C. Chr., Javanici, 
caespitosum, minus, laciniis breviorilms, colore atrofusco, textura crassiore:

LuzoN, Province of Pampanga, Mount Aiayat (3927 Merrill) October, 1904; 
Province of Bataan, Mount Mariveles (Loher) Marcli, 1897, alt. 1,400 m. 

2. Hymenophyllum serrulatum (Presl) C. Chr. Ind. 3G7 (//. Smithii Hook. 
Sp. Fil. 1: 97. Tah. 35 B). 

A species peculiar in the section Leptocionium by the valves of tlie sori being 
entire or very slightly dentate. A large species with ovate fronds 13 cm. long, 
7 cm. broad, the stipes 8 cm. hmg. It appears to be one of the most widely 
distributed species of the genus in tlie Pliilippines. 

LuzoN, Province of Bataan, Mount Mariveles (3233 Mcrrill) October, 1903; 
(165, 443, Whitford) May, July, 1904; (208 Copclaml) January, 1904; Province 
of Tayabas, Mount Banajao (918 Whitford) October, 1904; Province of Rizal, 
Angilog (Loher) March, 1906. Negros, Mount Silay (1509 Whitford) May, 1906. 

The same species has been found in Perak (leg. Hosc) ; the plant reported 
from Celebes under this name is doubtful. 

3. Hymenophyllum thuidium Harringt. in Journ. Linn. Soc. Bot. 16 (1877) 
26; Christ in Schum. und Lauterb. Nachtr. Fl. Deutscii. Scliutsgeb. Siidsee 1 : 34. 

A large very elegant species, all tlie foliaceous parts finely crisped and at the 
sanie time dentate-aristate. Very diaphanous, the sori sniall, globose, darlv brown, 
terminal, the valves entire. Stipe 6 cm. long; frond 10 cm. long, 5 cm. wide. 

MiNDANAO, vSan Ramon at 800 m. alt. (1751 Copeland) April, 1905; Mount 
Apo, at 1,800 m. alt. (1441 Copcland) October, 1905. 

Very nearly the same species is found in the Bismark Mountains, German New 
Guinea, leg Schlechter 14030, wliich I have called H. Bismarkianum.

4. Hymenophyllum aculeatum (v. d. Bosch Hym. Jav. Tah. 31, Leptocio- 
nium) Racib. Pter. Buitenz. 21. 

Luzox, Province of Bataan, Mount MariAcles (209 Copcland) Januarv, 1904;

ford) October, 1904. Mindanao, Province of Surigao (2G8 Bolsfcr) March, 190(i. 

Identical with speciniens from Mount Salak, Java, leg. Raciborski. It is the 
species enunierated in Bull. Herb. Boiss. 6: 141, as U. Neesii. 

5. Hymenophylium campanulatum n. sp. 

Leptocionium. Habitu omino II. Tunbndgensis, valvis integris, rhachi 

Dense et late caespitosuni, rhizoniate tenui sed rigido raniosissimo.

partitis, laciniis 4 aut 5, linearibus, vix 1 mm. latis, parce aristato-serratis. 
Soris raris, prope basin costae positis, peduuculatis, campanulatis, valvis 
erecto-patentibus ovatis, 3 mm. longis. Textura rigidiuscula. Colore 

Negkos, Mount Silay (1549 Whitford) May, 1900, alt. 1,100 m. 

6. Hymenophyllum pycnocarpum v. d. Bosch Hyni. Jav. Tah. 37. 

Laeve. Fronde ovata, tripinnatilida, rhachi alata. soris terininalibus 
paniculatis, valvis trigono-acutis. 

Luzox, Province of Laguna, Mount Maquiling (Lohcr) January, 1890, January, 
1906; Province of Tayabas, Mount Banajao (922 Whitford) October, 1904. 

HymenophyUnm suhdemissum Christ, Bull. Herb. Boiss. 6 (1898) 140, should 
be united witli this species. 

7. Hymenophyllum Blumeanum Sprcngcl, Syst. Veg. 4: 131. 

Luzox, Provincc of Bataan, Mount ^lariveles (3232 McrriU) October, 1903, the 
lanceolate form figured by Van dcn Bosch Hymen. Jav. Tah. 36, 2. H. polyaiithos 
Christ (non Sw.) Bull. Herb. Boiss. 6 (1898) 139, should be referred here. 

8. Hymenophyllum paniculiflorum Presl, Hymen. (1843) 32, 55. 

A small plant recognizable by its large sori which are ovoid or globose, 
terminal and occupying all the segments at the svunniit of the frond. 

LuzoN, Province of Benguet, ^Mount Tonglon, 2.250 ni. alt. (Lohcr) April, 1904. 
Identical with specimens from Java, leg. Giesenhagcn and Raciborski, and with 
specimens from Japan, leg. Fanric. 

I am now of the opinion that H. discosinn Christ, Bull. Herb. Boiss. 6 (1898) 
140, should be united with this species, although the sori are much broader and 
more round than those in the Javan plant, leg. Giescnhaycn. 

9. Hymenophyllum demissum (Forst.) Sw. in Schrad. Journ. 1800' (1801) 

Luzox, Provincc of Tayabas, ]\Iount Banajao (Lohcr) February. 1900. 

This plant is identical with the form found in Xew Zealand and Celcbcs, low, 
with small sori, the rachis winged only near the summit. H. productum Kze. 
Bot. Zeit. (1848) 305, Van den Bosch Hymen. Jav. Tab. .'/5, of Java, is a larger 
plant with kiangular elongated valves and winged stipes.

1,050 m. MiNDANAO, Province of Misamis, Mount Malindang (4638 Mcarns d 
Hutchinson) May, 1906. 

A form with very large sori and with broad segments. 

The Philippine plants refcrred by various authors to H. dilatatuin 8w., are 
referable to the two above species. 

12. Hymenophyllum australe Willd. Sp. Pl. 5: 527. 

LuzoN, District of Lepanto, Mount Data (1873 Vopcland) October, 1905; 
Province of Benguet, Mount Tonglon (Lolier) ; (5053 Curran) August, 1906. 
MiNDANAO, Mount Apo (324 DeVore c(- Hoover) May, 1903. 

The Pliilippine form has very narrow segments and is very compound, quadri- 
pinnatifid. Under the lens the margins are very finely denticulate.

Bosch Hymen. Jav. Tah. 2//. 

LuzoN, Province of Bataan, Mount Mariveles (3121 Merrill) October, 1903; 
(206 Copeland) January, 1904. 

This form, of the Cephalomancs group whicli is richly developed in the Philip- 
pines, is distinguishable by its rotuidcd piniiBe, its elongated aristate teeth and 
long sori.

Polysiichum. of the essentially Chinese gioup of P. auriculatum, is well lepre- 
sented in the Philippines. Tlie first form known was 1'hegopteris nervosa F§e, 
IMeni. 6. 13. Tab. 2. Fig. ^, wliich I do not hesitate to rediice as a variety of 
Puli/stichum deliodon. The rich Cliinese niaterial that I have at niy disposition

LuzoN, District of Bontoc, Sagada (1901 Copeland) November, 1905, alt. 
1,600 m. 

Very near the small group of P. hccatopteron Diels, and strongly resembling 
P. Dielsii Christ in Bull. Acad. Mans. (1900) 238, from whieh it differs in its 
smaller size, its short stipe, the pinnje not obtuse but pointed, the teeth more 
pronounced and the sori less marginal.

LuzoN, Province of Benguet, Trinidad (1812 Copeland) October, 1905, alt. 
1,200 m. 

Very close to the plant from Cliina, India, Annam (leg. Cadiere) and of Japan,

21. Aspidium (Pleocnemia) Angilogense Clirist. in P.ull. Tlprb. Boiss. II. 
6 (100(1) 1003. 

I do not lieaitate to refer liore Pleocnemia Cumingiana Preal, Epiin. Bot. 410, 
iiud regiet tliat tliis specific name wliicli has priority, is inappropriate in Aspidium 
beciuise of the later use of tbe sanie specific nanie under Af^}ii(Uum l)y sevcral 
autliors, Kunzc, Hlurm. In addition to tbe localities in Luzon cited l)y me in 
tbe ori<2final description of tbe species, Dr. Copeland bas found it in Mindanao, 
San Ramon, April, 190.5, No. 1098, alt. 000 m. He adds "Fronds 2 to 3 m. biKb, 
doltoid, stipe 2 m. bifib, stout, rbizome 10 to 20 cni. tbick, ascendinfj. I'rcsl, 
witliout doubt after Giming's notes says "arbor viginti-pedalis." In other 
characters I find our species to be ver_y near Nephrodium chrysotrichum Baker 
from Samoa; Upolu, Apia leg. lietche 1880; Falwao leg. Reinccke 90, 04; Savai, 
lcg. RrinecJcc OOb; Upolu, leg. Reinccke 04. The two collectors give tbe beight 
of tlie Samoan plant as from 20 to 40 feet, with black trunks. It is certainly 
tbe largest arborescent fern outside of tbe Cyatheaceae.

This speeies, widely distributed from British India, tliroughout Malaya, and 
in the Pliilippines especially, offers in the latter region a variability that ap- 
proaehes that of Dryoptcris cancsceus. The apices of the sterile leaves are elon- 
^ated into linear lash-like appendages which are proliferous and usually take root, 
the young pLants emitting a fascicle of leaves entirely different from those of 
tlie adult ones. Often thej' are not simple linear leaves. with the hiteral lobes 
more or less aborted, but frequently are singuhvrly compound, enhTrged and deeply 
incised. Often the little phmts are fertile, and the fertile fronds offer irregular- 
ities analagous to the sterile ones. In other characters the differences are 
frequently strongly marked, and the various forms might readily be considered 
to represent distinct species. I luive enumerated below the forms, that in my 
conception of this species, shoiild be considered as varieties or subspecies, and 
although several of tl)em have acquired a certain stability, certain characters are 
constant in all of them, showing their elose relationship to L. heteroclitus and 
probable derivation from that species.

Var. inconstans (Copel. in Govt. Lab. Publ. 28 (1905) 43 pro specie). 

In view of tlie fact tliat two varieties sliow a progressive intergradation 
between the type and the species described by Vopeland, I liave not hesitated to 
consider the latter as a variety of Leptochilus heteroclitus, a form still niore 
reduced than the preceding, cliaracterized by its very small size, the apices of the 
leaves often linear, the shoots vcry irreguLar. Var. Foxworthyi is almost exactly 
interniediate between the type and tlie variety inconstans.

This variety seems to be rather widely distributed in the Pliilippines; I have 
specimens from Christmas Island (Straits Settlements) leg. Ridley that closely 
approach it. 

Var. Linnaeanus (Fee Acrost. 87 pro specie). 

1 believe that this form can be reduced, with a sufficient degree of surety, as 
a variety of Leptochilus hcteroelitus, as a derived form of that species, in spite 
of its uniformly elongated and very narrow leaves. Its texture, its nerves, 
although strongly siniplified, its proliferous leaves and the strong resemblance 
of its offshoots to those of tlie normal form support this contention. We have 
tlien a series almost complete from the type, that seems to be always triphyllous 
in the Philippines, to the form with absolutely linear and undivided leaves.

LuzoN, rrovincc of Bc'nfi;uct, Baf^uio ((»012 lUmcr) Marcli, ]!»04. 

I have idcntified tliis ])lant after comparison with spccimcns from the Sand- 
wich Islands, lcf,'. llUkhnmd and Bnldmn, and from Ncw Calcdonia lcg. Franc. 
It is the form that Cvpelavd in his Polypodiaceaa; of the Philippincs, 84, supposes 
to be the variety Upinnatifidum of A. contiguum Kaulf., but it bdongs evidently 
in the section with A. cuneatum. 


Thc spccies of this genus oftcn can not bc dctcrniincd with ccrtainty without 
utilizing the characters shown by the secondary leaves. Unfortunately these 
sccondary lcaves are as yct imperfectly known in many specics, for frequently 
when adult and sorifcrous lcaves arc found, thc secondary lcaves arc not to be 
found, and without the threc forms and without tlie ccrtainty of their liaving 
come from the same plant it is often difficult if not impossible to idcntify these 
forms of Stenochlacna with trimorphous leavcs. 

Undertvood''' separatcs thc species of Strnoclilacua of the Old World, wliicli 
have the veins springing directly from the midrib, into two groups: 1, Tcrat- 
ophylhim with trimorphous leaves and with spiny naked rhizomes, and 2, 
Lomariopsis with rhizomes covered with scales but spineless. Howevcr, our 
knowlcdge of the last group is not sufficiently completc to dctermine whether or 
not the secondary leaves are prcscnt or lacking, but 1 am of the opinion that 
they are present, at least in some species. 

From the Philippines I am able to rccord the follov^^ing species: 

44. Stenoclilaena aculeata (Blume) Kunze Bot. Zeit. 6: 142. Loinaria 
aculcata Blume Enum. PI. Jav. 205.

(6264 Elmer) ; northern Luzon (Warburg). Mindanao, Mount Batangan 
( Warhurg ) . 

The secondary leavcs of tliis plant agree very avcII with those figured by Hookcr 
Sp. Fil. 1 : 56. B, for Davallia achillcuefolia Wall., \\hich is cited by Undericood 
as a synonym of *S'. aculcata. I do not hesitate to identify with this species the 
form described by Gopcland as Asplenium epiphyticum (Perk. Frag. FI. Philip. 
(1905) 184), and Dr. Copeland himsclf adniits in his Coniparative Ecology of 
San Ramon Polypodiacca^"' that this plant is "apparently idcntical with occasional 
immature forms of »S'. aculcata." This form constitutes simply, as I have denion- 
strated in Verhand. Schweis. Nat. Forsch. Ges. (190G) Tuh. 5, the nictamorphosis 
of the secondary leaves to thc adult ones, combined witli asplcnioid sori which 
ajipear on the metaniorphosed Icaves as a reminder of the origin of the genus, 
which is from the vicinity of Asplenium. I'have a specimen from Dr. Copclund 
which has beside scolopcndriform leavcs, a portion of the rhizonie with spines 
and with tripinnate leaves similar to those figured by Hooker for DuvuUia 

Copeland found his Asplenium cpiphyticum without the adult form of Steno- 
chlacna, which shows that the species of Stcnochlaena are not always normally 
develoiied, but remain sometimcs in a stunted condition. An analagous case is 
found in the Philippincs in Lcploohilus hctcroclitus.

The specimens agree well with the description of the species. The secondary 
leaves, wliich I presume belong with the specimens cited, but without being able 
to determine tliis point witli certainty, differ from thosc of tlie prcceding species 
in their linear, more elongated segments and with a tendency of the frond to 
become gradually larger and to present auricles at the anterior base of the 
pinnules, a point of union with Asplenium of the cuneatum group, conf. Verhandl. 
Schweiz. Nat. Forsch. Gcscll. (1906) Tab. 6. The secondary leaves mentioned 
above are those of specimens from Mindanao (Wurbury) , Luzon (Warburg) and

This species is distinguished by its very unequal and crenulate pinnae, one 
specimen with secondary leaves bearing also some adult leaves, which, although 
small, are strongly crenulate. The secondary leaves arc rather large, 10 cm. 
long, 4 cm. wide, nearly sessile, tripinnatifid, the rachis reddish, flexuous, the 
pinna; ovate, obtuse, 2 cm. long, 1 cm. wide; the pinnules serrate, cut into linear 
segments which are obtuse, often bi- or tri-furcate, 2 mni. long, 0.5 to 1 mm. 
wide, the color very dark green.

specimens from Montalban, Province of Rizal, Luzon, collccted by Loher in 
March, 1906, that agree exactly with Hoohcr's figvue, except that Lohcr's 
specimens are smaller, and have bi- to tri-pinnatifid fronds instead of tri- to

tlie copious free veinlets in tlie sterile frond. Tn my specimens of the species 
from Batavia, Java, ex Herb. Hort. Bot. Bogor., and from Celebes, leg. Harnsin, the 
veinlets are also very numerous, even as Ktirz himself shows in the figure cited 
above; moreover tlie constantly contracted fertile fronds of Hemionitis gymnopter- 
oidea are not a peculiarity of that species, as in my specimens from Montalban, 
leg. Loher, they are 1 cm. wide and present the oblique lozenge-shaped soriferous 
bodies as do the specimens from Java.

It does not form a nearly sessile rosette like the species, but the leaves are 
fascicled and stipitate and the sterile fronds, like the fertile ones, are pinnatifid 
and even pinnate. The size is miich larger. 

This form imitates strangely Leptochilus latifolius (Meyen) {Gymnopteris 
taccaefolia J. Sm.) in the protean variation of the fronds and in its habit. 
Normally to rate the large plant as a variety would not be comprehensible, from

the study of diied plants alone. without the evidence given by Copeland, and the 
absolute identity of the venation, tissue and its general structure. It is a 
striking examjile of the strange and luxuriant fornis found in the Pliilippines. 

Lcptuchilus latifolius is distinguisliable froni our pUint by its firm texture, 
not diaphanous, its color, black wlien dry, its proliferous fronds and its areola; 
supplied with a network of very irregular nerves. 

DicVs procedure in phicing Heniiouitis ZoUingcri in ^ipigramnic is to nie an 
unnatural arrangnient. Tlie ancestry of the plant is ratlier in the Aspidieae, 
anahigous to Stenoseiuia, and accordingly tlie above new generic nanie is proposed 
for it.

Tliis genus is in need of revision and contains a plurality of forms which 
doubtless can be studied with better results in the fiekl than in tlie herbariura. 
In addition to tlie ordinary form with bi- to tri-pinate fronds whicli are membra- 
nous and serrate, Copclaiid '* indicates, without name, another one that usually 
has entire and simply pinnate fronds. Tliis latter form is very close to one found 
iu China that I liave described as the variety spinulosa '^ but the Pliilippine 
form is larger and with nearly entire margins, and I call it:

81. Polypodium Sablanianum n. sp. 

1 have previously treated the polymorphism of the Microsorium '' type of 
which the best known representative is P. punctatum (L.) Sw. The present new 
*form, from its venation is almost exactly intermediate between P. punctaium Sw.. 
and P. myriocarpum ^lett. In the former, the lateral nerves are very regular, 
oblique, reaching the margin and inclosing 4 or 5 areolae, which are elongated, 
rectangular, between the rachis and the margins; these areolae are about equal, 
and the network of nerves is weak, inclosed in and more or less hidden by the 
fleshy tissue. In P. myriocarpum on the contrary, the lateral nerves do not 
reach the margin of the frond, and inclose only one large areola along tlie rachis 
and another narrower one between it and the margin, and the veins are strong 
and rather prominent. P. Hahlanianum has an even more delicate texture than 
/*. 7nyriocarpum, and its nerves are slender, not proniinent and form a single 
very large square areola, at the side of which is another very narrow obscure 
one. The plant is larger, 73 cm. long, 5.5 cni. wide, the apex of tlie frond long 
caudate, the base long decurrent, the stipe very short. Texture membranous, 
color bright green. the costa light yellow, shining. the fronds which appear to be 
solitary and not fascicled have undulate margins, the rhizome is climbing, 
brown, as tliick as a goose quill, eovered witli stitt' subulate dark l)r<»wn 4 mm. 
long scales.

This species was determined by Copeland as Vyathea Christii, Init it is 
distinguished from the latter by its axial parts being richly covered with 
furfuraceous scales, by the costse being covered with rounded intiated scales, by 
its membranous textvue and very reduced size.

March, 1897. 

A beantiful speeies characterized hy the shining liairs on the stipe and the 
shining white or inctallic scales on tlie nnder snrface of the segnients. 

This is the species that I liad previonsly identified "^ as .4. lepifera J. Sm., but 
1 am now convinced that it is a distinct species. The sliort description of 
A. lepifera J. Sm., given by Uooker " is quite insufficient froni which to identify 
Hmith's species, except tliat it appears to be near, if not identical with A. to- 
mentosa (Blume), as Christensen supposes in liis Index Filicum 44, or perhaps 
the same as Cyathea Loheri Christ. A. culocoma is distinguished from A. 
kiteirosa, with which it shares tlie character of the costal and costular scales, 
by its whitish scales and by its basal segments being free and attenuate toward 
the base, as well as by tlie marked glaucescenee of the frond. In A. latehrosa 
I have never observed the exce])tionally long scales wliich are shining, silvery or 
somewhat golden in color and strongly pointed, 4 to 5 cm. in length, such as are 
found in A. calocoma. It is a delicate species with trifurcate nerves and a very 
rugose rachis. 

Var. congesta (Alsophila lepifera var. congcsta Christ in Bull. Herb. Boiss. 
6 (1898) 137). 

This variety is identical with the type in having the same very large basal, 
scarious, silvery, subulate, 5 cm. long scales which are 4 mm. wide below,

yellowish rliachis wliich is very rough with small spines, small whitisli costular 
scales, aiifl tlie })asal segiiients free, reniote and narrowed below, but it is readily 
distinguishable from the type by its sliorter narrower segments which are more 
falcate and more strongly serrate. The pinnules do not exceed 8 cm. in length. 
In general appearance quite different from the type, but having the same essential 
characters. It appears to be an alpine form of the species.

The ordinary forni of this species so common in India, the Malayan Peninsula, 
Java, Borneo, Celebes and Amboina (herb. Christ), is not known to me from the 
Pliilippines, where the species is represented by a form notably larger. It is 
the same as with Alsophihi contaniinans, which is represented in tlie Philippines

MARATTIA Sinitli. 

All the Pliilippine fornis of tliis genus tbat 1 bave examined liave been identified 
after tlie classification in tlie nionograph of DeVricse and Hfirtinrf, in whicli work 
the diagnoses are by no nieans comparative and in wliicli the differences between 
related species are not noted. Tlie number of species is so large and tlieir 
characters so uniform that tlie distinctive characters of each species should have 
been emphasized. At any rate the group nierits more attention tlian the succes- 
sors to the two Dutch botanists have given it, for certainly the forms are very 
numerous and can not all be reduced to a single species. The morphological 
diflTerences between young and adult fronds are very great, and the latter, even 
the fertile ones, frequently present characters that are ordinarily found only 
in young fronds. In diagnoses tlie adult parts only liave been considered. 

I have been able to elucidate here, witb a fair degree of certainty, the 
following forms:

All tlie other species of Christcnscnia {Kaulfussia) known to me have the 
lateral pinnie rather strongly petioled. DeVriese and Harting have indicated in 
their Monograpli of the Marattiaceae 14, tliat the Kaulfiissia foiind by Guming 
in the Philippines, wliich was considerably smaller than the other known forms, 
might perhaps prove to be a distinct species. In comparison witli specimens from 
Assam, leg. King; Selangor, leg. Ridley ; Java, leg. Raciborski, and Sumatra, 
leg. Schneider, the specimens from Mindanao are very reduced. Tlie fertile 
frond is often simple and when it is tripartite the lobes are joined at the base, 
not petiohite, and very unequal, whitish beneath.

By H. CiiRiST. 
(Basel, Switzcrland.) 

Some timo ago IMr. Ehury D. McrrUlf Botanist of tlie Bureau of 
Seience, ]\Ianila, sent nie all the Philippine material of the genus 
Dryopieris from tho herharium of that institution, in order to give me an 
opportunitv to prepare a ehissified list of the spocios found in the 
Archipehigo. Tho colleetion contains many of Cuming's plants, and a 
large number of spccimens collected by the American botanists since 
the occupation of tlie Pliilippines by the United States. In additiou 
to the above material I have also received from Dr. E. B. Copeland 
a notaljlo collection, and Mr. Lolier has had the kindness to furnish 
me witli aii additional and very interesting collection, supplementary 
to the one he sent me in 1S9T and which was the basis of my work 
"Filices Insuhirum Pliilippinarum."^ Since the publication of the above 
paper some important works of Dr. CopeJand have notably advanced 
our knowledge of the ferns of the Philippines. In his Polypodiacea' 
of the Philipjnne Islands,- Dr. Copeland admits 60 species of Nephrodium, 
compiling the descriptions of all the species credited to the Philippines, 
even of those spocies of which he had not seen specimens. In my present 
paper I have not attempted to account for all the species of the genus 
that have been credited to the Archipelago by various authors, but 
have considered only those of which specimens are before me. In a 
group so difficult as Dryopteris and so subject to diverse interpretation, 
it appears to me that tlie hitter treatment is the surest, even if com- 
pleteness is sacrificed. 

I have limited Dnjopleris iu tho sense of Christensens ludex Filicum; 
that is, excluding Pleocnemia and Sagenia and treating only Lastrea 
{mchiding PJiegopteris) and Nephrodium propor (including Goniopteris, 
^ Mesochlaena and Meniscium). As the Philippines are particuUirly 
^ rich in speeies and forms of Dryopteris, the task of troating all the 
*"' species was sufficiently arduous. In regard to nomenclature I have 
^^ followed Christensens Index Filicum and accepted tlie generic name

190 CHRIST. 

Dryopteris, in spitc of the sacrifice of personal opinions and in spite 
of being obliged to diseard nanies tliat have been in constant use for a 
century and which are known to all botanists. 

JSTowhere else is the tyj)e of Nephrodium witli anastomosing veins so 
diversified as in the Diiiippines. There are in the Pliilippines fornis 
with very narrow pinna3, and sonie special characters are found in the 
species of this region niore often tlian in tliose of other parts of the 
worhl. These characters are: Pinna? attenuated toward their, 
tht! lower ones defiexed, tlie pinnae degenerating into auricles at the l)ase 
of the frond^ sometimes abruptly, sometimes gradually. In otlier equa- 
torial regions species with these characters are ratlier rare. In tropical 
America, Dryopteris sagittata (Sw.) is ahnost the only Imown species 
of the group where the frond is abruptly reduced at the base, the lower 
pinnae being represented by auricles, and D. refracta (Fiscli. & Mey.) 
is one of the rare examples of a species with deflexed pinnse. The Ma- 
layan region offers tlie most frequent examples of species presenting 
tlie two last cliaracters, for example D. sagittifoUa (Blmne) of Java, 
but even in tlie Malayan region sucli species do not approacli in number 
tliose of tlie Philippines. 

There is in the Pliilippines a tendency to "insular" reduced types 
wliicli is ratlier interesting. These reduced types elsewliere are rare, 
and abnormaL Tlie irregularity and reduction of the fronds and even 
tlie dimorphism of tlie fertile fronds is normal in Dryopteris canescens 
(Blume) as found in the Pliilippines, and D. glandulosa lias analogous 
tendencies. Tliese variations do not as yet appear to be constant, and 
they offer some subspecies and varieties of doubtful value, wliich are 
discussed later under the two above species. In the Arcliipelago more- 
over are analogous variations in otlier genera, for example tlie singularly 
stunted forms that are grouped under Leptochilus heteroclitus (Presl) 
{Acrostichum fiagelliferum Wall.), and some species of Pteris, sucli as 
P. ensiformis Burm., and P. heteromorpha Fee. In the West Indies, 
Cuba, J amaica, Porto Eico, Santo Domingo, etc, analogous insular f orms 
are foimd in Polystichum, Fadyenia, Sagenia and especially in Dryopteris 
reptans (Gmel.) which tliere offer multiple reduced forms. I am sure 
that the very prolonged isolation of tliese arcliipelagoes plays some role 
in tlie occurrence of tliese variations, althougli it is not possible at present 
to specify just wliat this influence is. 

Tlie wonderful variations of Dryopteris canescens, which are foimd 
in otlier parts of Malaya (Celebes) only as rarities, but which are 
developed in the Philippines into a bewildering series of forms, appear 
to me to tlirow some new light on the "aberrant forms" of the old 
scliool of pteridologists. By the variations of Dryopteris canescens, 
which present an unbroken and insensible transition from a true Neph- 
rodiuiii to a plant entirely achrosticlioid as to tlio sori, tlie affinity of 


LeptocliUus. Gymnopteris, Polyhotrya, Egenolfia, Stenosemm, and Cae- 
noptens with Aspidimn, m a broad sense, appears to me to acquire a new 
support; and wliat is more, although perhaps in the cases where it has 
not yet been possible to iind tlie aspidioid type of all acrostichoid plants 
it is probable that the aspidioid type has not been preserved or that it 
has been so modified as to be unrecognizahle. Be that a^ it may 
for Stenosemm one must admit the immediate descent of Pleocnenda 
memhramfoliu {Dictyopteris Chattagramica Clarke) as Beddome has 
asserted.'^ Likewise I now connect my Gymnopteris Bonii ' from Tonkin 
directly with Aspidium repandum Willd. The contention that "Acros- 
tichum" is only "Aspidium" with reduced fertile pinn^, appears to me 
to be better established ever. Is this a step iu advance in the 
development or a degeneration ? The example of Dryopteris canescens, 
where the mcontestable deformation of the pinna^ both fertile and 
sterile, is accompanied l)y the acrostichoid formation as to the soriferous 
parts, appears to me to point strongly to the latter; that is to say, 
an aberration and weakening of tlie type, wliich one can scarcely call 
only teratological, because the influences that liave caused the cli"anges 
are uuknown. 


1. In my Filices Insularum Philippinarum '' I have noted Aspidiiim 
Fauriei var. elatiits Christ and A. grammitoides. Both belong in Atliy- 
rium, with aspidioid sori, as is the case witli Athyrium o.typhy]1am whieli 
is found in the Philippines with absolutely aspidioid sori. 

2. In his Polypodiaceaj of the Philippine Ishmds," Copeland includes 
Nephrodium asperulum (J. Sm.) Copel. The species was based on No. 
(i3 Cuming, Polypodium asperulum J. Sm., and the specimen in the 
Herbarium of the Bureau of Science is to me Microlepia speluncae 
(Linn.) Moore, with submarginal sori. 

3. Copelnnd' admits Ncphrodium rugulosum (Labill.) Copel., but to 
me the phmt indicated is Hypolepis. Species of llypolepis with the sori 
more or less intramarginal give rise to some doubt as to their proper 
disposition. There is a form in the Philippines which has a rhizome 
often, if not always, creeping, which is generally a good character of true 
Hypolepis and which indicates the relationship of that genus with 
Pteridium. This form was considered by me at first as Dryopteris 
setigera (Blume) 0. Ktz., and later as Aspidium vile Kunze, of Java, 
with which it has a great resemblance. It has been collected on Mount 
App, Mindanao, by Gopeland (No. 1462) October, 1904, and on Mount

The Philippines share with Celebes a plurality of forms of this species, interest- 
ing because of the numerous more or less "insular" forms into which it is 
divided. I refer the reader to what I have said regarding it in Ann. Jard. Bot. 
Buitenzorg 1. c, wliere I have showTi its affinity to the group containing P. 
parasitica of which it appears to be a weakly derived species, weakly derived 
because of its generally reduced dimensions, the indusium frequently lacking, 
and its sori irregular, but above all in the variation in the form of the fronds 
which present all forms of pinnse from those linear and clongated to those 
variously cut, lobed and dilated in a most bizarre manner, and finally in the 
dimorphism and narrowness of the fertile fronds Avhich have niuch elongated 
stipes and the pinnse so narrowed that the sori lose their distinctness and form 
a mass which entirely covers the narrow fertile pinnse, in this latter respect 
resembling those of Egenolfia appendiculata. 

In Celebes I have distinguished three forms — nephrodiformis, which is scarcely 
dimorphous; gymnogrummoides, with the fertile fronds somewhat reduced; and 
acrostichoides with the fertile pinnae narrowly linear. For the species as it 
occurs in the Philippines, this distinction does not suffice, and it is necessary to 
distinguish a large number of forms, some of wliich have acquired the value of 
subspecies, or perhaps in some cases, of species. These forms I characterize as 
follows : 

Var. lobatum n. var. 

Statura minore, stipite longiore (20 cm., frondis 20 cm.) pinnis niinus 
numerosis, latioribus, lobis latioribus, paucioribus, profundioribus nervis 
flexuosis, interdum irregularibus, aream unam costalem forinanti])us, 
pubescentia sensiore grisea imprimis costas nervosque tegente, et soris 
indusiis carentibus, saepe irregulariter elongatis.

guet, Baguio (1866 Cojicland) November, 1905. 

Java, Celebes. 

This variety more or less resembles the large form figured by Blume and 
approaches a small D. parasitica, but the stipe is relatively longer, 20 cm., the 
frond 20 cm., the pinnse less numerous, longer, the lobes longer and more numerous 
and more deeply divided, the nerves very undulating, forming one costal areola, 


Vcar. degener n. var. 

Ehizomate elongato subrepente, pinnis ovatis saepe obovatis basi 
attenuatis, obtusissimis, obtuse crcnato-lobatis, apice frondis elongato 
lato obtuse lobato, pinnis sterilibus brevius (G cm.) fertilibus saepe longius 
(usque ad 35 cm.) stipitatis, pinnis fertilibus remotis, soris irregulariter 
sparsis plus minus rotundis. Tota planta a 20 cm. us^jue ad 43 cm.

Apparently common and widely distributed in the Pliilippincs; endemic. 

This is a form of the D. omwscens group, but so accentuated, and at tlie sanie 
time so widely distributed (it should be one of tlie most common ferns in the 
Archipelago), that it should be recognized as a subspecies. A small plant, almost 
turf forming with elongated, weak and often running rhizomes, the fronds not, 
or but littlc dimorphous, the pinnse few, short, broad, nearly square and very 
irregularly lobed, the lobes sometimes short and obtuse, sometimes greatly 
elongated. The specimens witli the elongated pointed pinnte have the appearance

tlie pinnse toward the apex and the increasing length of thc lobes toward the 
tips of the pinnse is more accentuated. The sori are large, marginal, bordering 
tlie lobes in a single series and tlie plant has not the harshness and grayish color

:Mindoro, Baco River (168 McGi-egor) April-May, 1905. 

This is tbe typical form of Blume's species, of wliicb I bave identical material 
from Java, Tjipoes, leg. Raoihorski, and from Perak, leg. Hose, and difFers from 
tbe plant of nortbern India (Meniscimn longifrons Wall.) in its flesby-papyraceous 
texture, opaque, tbe areolse less numerous (8 to 12, rarely more) more or less 
concealed under tbe membranous epidermis and not costellate and prominent. 
Tbe proliferous sboots in tbe axils of the ujiper pinnae are also present in tlie 
Pbilippine plant, as indicated by Blume in tbe Javan form. 

Christensen in bis Index Filicum unites this species, althougb with doubt, 
with Dryopteris urophylla ; bowever tbe proliferation in Blume's species, and the 
membranous epidermis covering and in part concealing the areolae sharply 
distinguishes D. cuspidata from D. uropbylla. D. longifro-ns differs in having a 
very smootli sliining surface, tbe areolae in strong relief, and in tbe form of its 
pinnae whicb are elongated and witb tbeir margins nearly parallel. In regard 
to tbe elongated sori, I bave from Java a specimen witb tbem nearly round. It 
goes witbout saying tbat diagnoses alone are of little value in indicating tbe 
diflferences in forms and the sligbt cbaracters tbat distinguisli tliese undivided 
species of Dryopteris; cbaracters tbat strike the eye on examination of specimens 
are often diflicult to express in words in tbis and parallel cases.

This species has been knoun to me for a long time, but was considered as 
Lastrea UguUita J. Sm. It is described here from the most common form — that 
is, rather small specimens — although sometimes it attains a size three times 
as large as is indicated in the diagnosis, and even larger. The plant can always 
be readily distinguished from D. immersa and D. ligulata (which to me are not 
specifically distinct) by its very sharp segments, which are cmieate and deeurrent, 
and by its light green color and more firm texture. Its aflinity is with D. 
Koordersii Christ * of Celebes, but that species is distinguishable by its very 
peculiar indusium which I have described as follows : "Indusio subgloboso lateral- 
iter inhaerente duro crustato vakle convexo brunneo nitido adiapliano sorum 
margine deflexo (more Matoniw) tegente."
